I have written a javascript function that uses setInterval to manipulate a string every tenth of a second for a certain number of iterations. function timer() { var section = document.getEleme...
289. setInterval sets up a recurring timer. It returns a handle that you can pass into clearInterval to stop it from firing: var handle = setInterval(drawAll, 20); // When you want to cancel it: clearInterval(handle); handle = 0; // I just do this so I know I've cleared the interval. On browsers, the handle is guaranteed to be a number that isn ...
The default behavior of setInterval is to bind to the global context. You can call a member function by saving a copy of the current context. Inside retrieve_rate the this variable will be correctly bound to the original context. Here is what your code would look like: var self = this; this.intervalID = setInterval(.
@Alnitak, right because that is the only thing bad about setInterval. sigh. How about the fact that if the elements get removed, setInterval will keep causing errors unless you do some redundant defensive code. sigh. –

setTimeout(expression, timeout); runs the code/function once after the timeout. setInterval(expression, timeout); runs the code/function repeatedly, with the length of the timeout between each repeat. Example: var intervalID = setInterval(alert, 1000); // Will alert every second. // clearInterval(intervalID); // Will clear the timer.

Example: setTimedInterval (callback, 100, 1000); if callback execution is >1 00ms, then it will be probably fired a few times not 10 times.
function myFn() {console.log('idle');} var myTimer = setInterval(myFn, 4000); // Then, later at some future time, // to restart a new 4 second interval starting at this exact moment in time. clearInterval(myTimer); myTimer = setInterval(myFn, 4000); You could also use a little timer object that offers a reset feature: function Timer(fn, t ...
Oct 27, 2017 · If you don't care if the code within the timer may take longer than your interval, use setInterval(): setInterval(function, delay) That fires the function passed in as first parameter over and over. A better approach is, to use setTimeout along with a self-executing anonymous function:
